Due to some significant changes in the OS, a system administrator wants to see which remotely accessible services are enabled by default to assess the security risk prior to upgrading to the new version. Which of the following utilities should the administrator use?

Accepted Answer

A port scanner is used to identify open ports and services running on a system, which helps assess security risks associated with remotely accessible services.

Question 4

A server administrator implements external storage for a file server. At a later time, another administrator wants to extend this storage to a second server but is unable to connect to two servers simultaneously. Which of the following storage types was implemented by the first administrator?

Accepted Answer

DAS (Direct Attached Storage) is directly connected to one server and cannot be shared between multiple servers simultaneously without additional networking or configuration.

Question 5

A technician would like to restrict when internal hardware components on the server are accessed. Which of the following server hardening techniques should the technician implement?

Accepted Answer

A chassis lock physically secures the server case, preventing unauthorized access to internal hardware components.

Question 6

A system administrator is given a server with an existing OS installed and four empty SAS bays. The system administrator is asked to set up a new data drive for testing with 100GB of data. For the best possible performance, which of the following should the system administrator select for the data storage?

Accepted Answer

Solid state drives (SSDs) offer the best performance in terms of speed and reliability compared to other options like SCSI, SATA, or flash drives.

Question 7

When using multifactor authentication, which of the following represents "something you have"?

Accepted Answer

An ID card represents "something you have" as it is a physical object that can be possessed by the user.

Question 8

A technician has access to a recent full backup. Data has changed since the last backup. Which of the following provides the fastest restore while minimizing backup size?

Accepted Answer

A differential backup captures all changes since the last full backup, allowing for a faster restore than incremental backups while minimizing backup size compared to full backups.

Question 9

An administrator sees a message in the system console that a drive is bad in the single-volume JBOD storage array. A few minutes later, a user calls the help desk to report an inability to read a file from a mapped drive. Which of the following should the administrator do?

Accepted Answer

In a JBOD (Just a Bunch Of Disks) configuration, there is no redundancy or parity, so if a drive fails, the data on it is lost. The administrator should replace the failed drive and restore the data from the last backup.

Question 10

A technician is installing a server using a two-channel RAID controller, using RAID1 for the first channel and RAID5 for the second channel. If the technician has six 1TB disks total, how will this configuration look?

Accepted Answer

RAID1 requires two disks for mirroring, and RAID5 requires a minimum of three disks. With six disks total, two can be used for RAID1 and the remaining four for RAID5.

Question 11

A technician has connected a previously formatted ext4 eSATA drive to a Linux server. Given the following output: Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 382818 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 - 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0009f31a Device Boot Start End Blocks Id System /dev/sdb1 * 20481 953525168 976761560 83 Linux Which of the following commands should the technician use to make the partition available under /data/drive0?

Accepted Answer

The 'mount' command is used to attach the filesystem found on /dev/sdb1 to the directory /data/drive0, making it accessible.

Question 12

An administrator thinks that a particular network connection is dropping packets. Which of the following tools would the administrator use to BEST identify where the packets are being dropped?

Accepted Answer

Tracert (or traceroute) is a network diagnostic tool used to track the pathway taken by a packet on an IP network from source to destination. It helps identify where packets are being dropped by showing each hop along the route and the time taken for each hop.

Question 13

Which of the following authentication protocols could be used to authenticate network administrators at a datacenter to manage switches over a remote SSH connection? (Select TWO).

Accepted Answer

TACACS and RADIUS are both authentication protocols used for network devices. TACACS is often used for network device administration, while RADIUS is used for network access authentication, both of which can be used to authenticate administrators managing switches over SSH.

Question 14

Multiple users report that an application attempting to open a file retrieved from a server reports that the file is corrupted. Which of the following applications can be used on the server to verify file integrity?

Accepted Answer

A checksum application can be used to verify the integrity of a file by comparing the calculated checksum value of the file with the expected value to ensure it has not been altered or corrupted.

Question 15

A new server has two drives and a RAID controller. Which of the following is an option for configuring the storage on this server?

Accepted Answer

RAID 0 is an option for configuring storage with two drives, as it requires a minimum of two drives and provides striping without redundancy. RAID 5, RAID 6, and RAID 10 require more than two drives.

Question 16

An email administrator is tasked to setup a Linux mail server. One of the requirements is to close all ports except SSH, HTTPS, SMTP, POP3, and IMAP4. Which of the following commands should be used to see which ports are currently open on the mail server? (Select TWO).

Accepted Answer

The `lsof` command can list open files and the network connections associated with them, which includes open ports. The `netstat` command can display network connections, routing tables, and a number of network interface statistics, including open ports.

Question 17

A datacenter audit finds that a number of personnel are not using access cards when entering a secured area with a coworker. Which of the following security methods could be implemented to help prevent this behavior?

Accepted Answer

A mantrap is a physical security method that can prevent unauthorized entry by ensuring that only one person can enter at a time, thus preventing tailgating.

Question 18

An administrator has been tasked with making recommendations for purchasing new disks for a low I/O file server. Keeping in mind that budget and capacity are the primary concerns, which the following disk types should the administrator recommend?

Accepted Answer

SATA disks are typically more cost-effective and offer larger storage capacities, making them suitable for low I/O environments where budget and capacity are the primary concerns.
